Solvent-induced two heterometallic coordination polymers based on a flexible ferrocenyl ligand

New Ferrocene-Based Metalloligand with Two Triazole Carboxamide Pendant Arms and Its Iron(II) Complex: Synthesis, Crystal Structure, 57Fe Mössbauer Spectroscopy, Magnetic Properties and Theoretical Calculations

“…Unfortunately, as a result of the low solubility, all experiments to prepare crystals suitable for X-ray structure analysis through recrystallization from different solvent systems or using different temperature gradients, slow diffusion, or hydrothermal synthesis were unsuccessful. Bidentate ferrocene-based ligands containing flexible spacer, including amide group, are inclined to form oligomers or low -dimensional polymers [17][18][19][20][21]. Based on this fact and the results of analyses, we suppose a polymeric structure of the Fe II complex 1.…”

“…[10][11][12][13][14] Two kinds of ferrocenyl derivatives have been widely used as ligands: ferrocenyl-based carboxylate [15][16][17][18][19] and pyridine-containing ferrocene.
